Covalent organic frameworks (COFs) are an emerging kind of porous crystal material.
The efficient spatial separation of charges is crucial for augmenting the photocatalytic efficacy. Herein, a CoOx@CdS core-shell hererostructure fabricated by photodeposited amorphous CoOx cover surface 3D CdS highly hydrogen evolution (PHE). Amorphous extends optical absorption range, suppresses photocorrosion and enhance specific area CoOx@CdS. Consequently, optimized 2%CoOx@CdS exhibits superior PHE activity (16.30 mmol h-1 g-1) outstanding photostability beyond 70 h was also obtained,...
Addressing the pressing and significant issue of reducing greenhouse gas emissions in our society, it is crucial to develop environmentally sustainable materials for carbon dioxide adsorption. In this work, we propose a straightforward effective method, that is, situ growth covalent organic frameworks (COFs) on polyacrylonitrile (PAN) nanofiber substrate using reversible polycondensation termination technique successfully prepare flexible COF membranes (PANm@BTCA-TPB APANm@BTCA-TPB COF)...
An entropy-cloud model is proposed to deal with soil heavy metal pollution assessment based on entropy and cloud theory.Parameters of the each level are calculated chosen indicators, hybrid weights determined Shannon analytic hierarchy process (AHP) generate an all indicators.Certainty degrees by model, fuzzy certainty indicate complexity pollution.Heavy 10 farmland soils in mining areas assessed model.Comparative studies variable sets, artifi cial neural network, normal show that effective...
Shanxi-aged vinegar, a traditional Chinese grain-fermented food that is rich in polyphenols, has been shown to have therapeutic effects on variety of diseases. However, there no comprehensive evaluation the anti-inflammatory activity polyphenols extracted from vinegar (SAVEP) date. The activities SAVEP, both RAW 264.7 macrophages and mice, were extensively investigated for potential application SAVEP as novel agent. In order confirm notion could improve inflammatory symptoms, was firstly...
Abstract This paper investigates the operation inspection and anomaly diagnosis of transformers in substations, carries out an application study artificial intelligence-based sound recognition technology transformer discharge to improve timeliness diagnostic capability intelligent monitoring substation equipment operation. In this study, a parameterization field is used implement automatic detections. The samples are pre-processed then Mel-frequency cepstrum coefficients (MFCCs) extracted as...
The adsorption capacity of a solid amine adsorbent for CO2 is often limited by the number amino groups on surface. In this paper, kind ultrafine fiber (PSN) was prepared direct electrospinning polyethylenimine blends, which could provide plentiful surface without further modification and would improve utilization efficiency fibrous adsorbent. effects structure performance PSN investigated. results indicated that higher outer area can greatly its rate CO2. Under simulated flue gas conditions...
Anomaly detection of the hydro-turbine operating status is required to achieve safe monitoring hydro-turbines. The anomalies based on sound signals pertains acoustic scene recognition. In this study, features were extracted MobileFaceNet neural networks. Using feature vectors, an improved Gaussian Mixed Model (i-GMM) was built, and anomaly test samples performed. effectiveness i-GMM model method verified be capable achieving 100% bearing data set. collected from different measurement points...
Solid amine adsorbents are promising materials to mitigate global warming. In this study, a commercially available melamine-formaldehyde sponge was adopted as support prepare kind of solid adsorbent using polyethylenimine functional component and ethylene glycol diglycidyl ether cross-linker. The adsorbent, with abundant tunnels high loading amount, had adsorption capacity. When the 89.6 wt%, as-prepared showed capacity 7.29 mmol/g at 20 °C in presence water. spent could be easily...
A simple graph G is C_4-induced saturated if contains no induced copy of C_4 , but deleting any edge or adding G^c to creates such a copy. Behrens, Erbes, Santana, Yager and Yeager in [2] proved the existence C_4-induced-saturated graphs by presenting some constructions with at least 12 vertices. In this paper, we develop properties on graphs, show that there less than vertices up isomorphism, only one
The silicon anode has been anticipated for utilization as the electrode material in forthcoming generation of high specific capacity lithium-ion batteries. However, severe pulverization caused by large volume change during cycling and its own poor electronic conductivity result terrible rate-performance cycle stability. To surmount those challenges, we devise a carbon@silicon composite with bio-inspired root-nodule structure that not only mimics root legumes but also demonstrates analogous...
Rolling bearings in operation will appear nonlinear characteristics of the fault vibration signal. In process feature extraction, a single permutation entropy (PE) produces unsatisfactory results and low accuracy. this paper, new diagnostic method was proposed, which based on variational mode decomposition (VMD) multiscale (MPE) to diagnose analyze rolling bearing faults, multi-scale aligned features intrinsic function (IMF) faulty signals were extracted, then support vector machine (SVM)...
